ZHCSDF4F May 2014 – March 2018 DRV2604L
PRODUCTION DATA.
The DRV2604L device supports a wide range of voltages in the input. Ensuring that the battery voltage is high enough to support the desired vibration strength with the selected actuator is an important design consideration. The typical application uses Li-ion or Li-polymer batteries which provide enough voltage headroom to drive most common actuators.
If very strong vibrations are desired, a boost converter can be placed between the power supply and the VDD pin to provide a constant voltage with a healthy headroom (5-V rails are common in some systems) which is particularly true if two AA batteries in series are being used to power the system.
